Usage
This template rounds parameter 1 by parameter 2 decimal places (goes the other way for negative rounding) and includes trailing zeros.
{{Round|54.376|2}}{{Round|54.376|-1}}{{Round|68.4273E12|-10}}
For example, rounding by 1 gives 1 decimal digit, rounding by 0 gives integers, or rounding by -2 gives the amount in hundreds. Scientific notation is displayed for numbers greater than or equal to 1×109, or less than 1×10−4.
Examples
{{Round|2.0004|3}}- {{expr:2.0004 round 3}} → 2
{{Round|0.000020004|7}}{{Round|0|8}}{{Round|154268|-3}}{{Round|154568|-3}}{{Round|1200004|-1}}- whereas {{expr:1200004round-1}} → 1200000, even though {{expr:1300004round-1}} → 1300000 (see m:Help:Format produced by expr)
{{Round|1300004|-1}}{{Round|4.1e6|9}}{{Round|4.1e6|10}}{{Round|1542689271|-7}}{{Round|1542689271|2}}{{Round|7e9|-9}}{{Round|-123|1}}{{Round|-1200007|-2}}{{Round|-1234567899|-7}}
As with #expr, the total number of significant digits is not more than 14:
{{Round|1234567890.123456789|10}}{{Round|123456789.0123456789|10}}{{Round|.0001234567890123456789|20}}
- The second parameter, precision, should be an integer. Non-integer may give unexpected result.
{{Round|1.234567}}{{Round|1.234567|2}}{{Round|1.234567|2.3}}{{Round|1.234567|2.7}}
TemplateData
This is the TemplateData documentation for this template used by VisualEditor and other tools.
Round
Rounds (parameter 1) by (parameter 2) decimal places, and formats. Scientific notation is used for numbers greater than 1×10^9, or less than 1×10^−4.
| Parameter | Description | Type | Status | |
|---|---|---|---|---|
| number | 1 | The number to be rounded | Number | required |
| decimal places | 2 | The number of decimal places, if negative the number is rounded so the last (parameter 2) digits are zero | Number | required |
